- The mystery of a dying star’s final kick
Researchers propose that aging stars receive thousands of small velocity boosts as they shed layers, leading to a final kick that alters their trajectories and can disrupt binary star systems. The findings, presented at the American Astronomical Society meeting, suggest these kicks result from asymmetric ejection of material during the red giant phase, with cumulative effects reaching up to 1 kilometer per second for resulting white dwarfs.
